DiskReadTask -> DiskReadTaskInterface, DiskReadFileTask -> DiskReadTask, same thing for the write side. Changed the includes files accordingly

They are sorted into several categories : WIP, Not touched, updated. See the color legend in the file

They were used for test purpose, but Mock objets are better for that, so removed

Otherwhise, after catching up an exception saying we failed to report, we did not leave the loop

This fixes UINT64_C not defined in SLC5.

For instance, we can now ensure client.reportEndOfSession(WithError) is the last function called and check we have the right number of report

ReportEndofSession(WithErrors)::goingToEnd returns now true as it should and RecallReportPacker.M-terminate has been removed by goingToEnd+break if true

Moved all files related to Client to client/, changed the namespace and fixed the files consequently (header,usings,...)

Modified the FakeClient consequently and the CMake files too

Relaxed constrain on frequency for flusing report and added logging&report to client in case of mismatch between the report's type for the end of session and the presence of an error
Now we call reportEndOfSessionWithErrors if there is an actual error or a mismatch (that implies a bug in the code). Flushing is done as soon as the number of reports is >= frequency (instead of >)

Add logging and report to client in case of mismatch between the report's type for the end of session and the presence of an error
Now we call reportEndOfSessionWithErrors if there is an actual error or a mismatch (that implies a bug in the code)

Removed the exception launcher which was not used anywhere and duplicates the one of castor::exception::Errnum.

MemBlock, MemManager, MemManagerClient, MigrationJob,
TapeReadFileTask, TapeReadTask, TapeSingleThreadInterface,
TapeReadSingleThread, TapeWriteTask, TaskInjector
into castor::tape::tapeserver::daemon

Fixed tapeserver-mm which makes use of some of the moved classes.

We currently only cover the Recalls, and we still need to start the threads.

intended for protyping.
Retyped DiskWriteThreadPool's members to fixed length types.
